Profinite properties of RAAGs and special groups
arXiv:1603.07197 · doi:10.1112/blms/bdw056
Abstract
In this paper we prove that RAAGs are distinguished from each other by their pro- completions for any choice of prime , and that RACGs are distinguished from each other by their pro-2 completions. We also give a new proof that hyperbolic virtually special groups are good in the sense of Serre. Furthermore we give an example of a property of the underlying graph of a RAAG that translates to a property of the profinite completion.
